Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional push-pull circular connectors are used with fixed concentric arrangement of connection element and locking element body, then structural simplicity is maintained, but insertion difficulty increases and damage risk occurs due to insufficient alignment tolerance

Engineering Contradiction:
Improveinsertion easeVSAvoidconnector structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The locking element body is made movable relative to the connection element through a coupling mechanism with the shielding element. This allows the locking element body to dynamically adjust its position during insertion to accommodate misalignment between the connector and complementary plug-in element, transforming the rigid fixed arrangement into a flexible adaptive structure that absorbs alignment errors without requiring excessive insertion force

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If the connection element and locking element body are firmly connected in conventional designs, then manufacturing precision requirements are reduced, but alignment tolerance during insertion is insufficient causing damage risk

Engineering Contradiction:
Improveconcentric alignment precisionVSAvoidconnection reliability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The coupling mechanism between the shielding element and locking element body enables relative movement, allowing the system to compensate for manufacturing tolerances and alignment errors that occur during assembly. This dynamic adjustment capability ensures reliable engagement of the locking element body with the complementary locking element body even when initial alignment is imperfect, preventing damage while maintaining connection reliability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The coupling mechanism acts as an intermediary between the connection element and locking element body, mediating their relative positions. This intermediary structure allows the locking element body to be positioned at a distance from the connection element while maintaining functional connection, providing the necessary alignment tolerance without compromising the overall structural integrity or connection reliability

Inventive Principle:
Principle #24Intermediary (Mediator)
